PATCH [7/n]: Prepare x32: Use Use long long builtin for x86-64

[H.J. Lu]

Hi,

long may be 32bit for x86-64. But long long is always 64bit.  This
patch uses long long builtin for 64bit.  OK for trunk?

Thanks.

        * longlong.h (count_leading_zeros): Use long long builtin for
        x86-64.
        (count_trailing_zeros): Likewise.
